gh-98030: socket: add missing TCP socket options (#98031)

Browse source 
A few TCP socket options have been added to the Linux kernel these last
few years.

This commit adds all the ones available in Linux 6.0:

  https://elixir.bootlin.com/linux/v6.0/source/include/uapi/linux/tcp.h#L91

While at it, the TCP_FASTOPEN option has been moved lower in the list
just to keep the same order as in tcp.h to ease future synchronisations.
